Installation / Operation Instruction Manual

THE FOLLOWING INSTRUCTIONS ARE FOR INSTALLATION

OF:

GAS WATER HEATERS SUITABLE FOR WATER (POTABLE)

HEATING AND SPACE HEATING

(Replaces pg. 31 in instruction manual.)

All piping components connected to this water heater for space heating applications

must be suitable for use with potable water. In Massachusetts, space heating piping

length must not exceed 50 feet.

1. Toxic chemicals, such as those used for boiler treatment, must not be introduced

into potable water used for space heating.

2. This water heater must not be connected to an existing heating system or

component(s) previously used with a non-potable water heating appliance.

3. When the system requires water for space heating at temperatures higher than

required for other means, such as an ASSE approved mixing valve must be

installed to temper the water for those uses in order to reduce the scald hazard

potential.

Please refer to Figure 6 for suggested piping arrangements.
